"""Seed a Hermes state.db with a session exported from a real conversation.

Usage: seed_session_db.py <state_db_path> <fixture_json_path>

Creates the database with the full SessionDB schema (if it doesn't exist)
and imports the session from the JSON fixture. Uses the real
SessionDB.import_sessions() so the data shape matches what the desktop
backend expects.
